To ALL .WHOM 1r M AY coivonnlv;

Be it known that I, C. S. BAKER, of Manchester, in the county ofHillsborough, and State of New Hampshire, have invented a new and usefulimprovement in Invalid-Bedstead; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art toimake and use thesame, referencebeing-had to the accompanying drawings, forming part of thisspecification', in which- Figure l is a top vie'w of my improvedbedstead.

Figure 2 is a. verticallongitudinal section of the same, taken throughthe line z x, fig. 1, and showing in red lines the foot part lowered andthe head part raised. i

I Similar letters of reference indicate like-parts. v

My invention has fo;` its object to improve the constructionjof theinvalid-betistoad patented March 27, 18,66, 'Warren S. Hill, inventor,and assigned to me, so as to make it sinjplcr and less expensive inconstruction and more efficient in operation; and it consists inlowering and raising the foot part ofthe beclstead by toothed segmentsoperated by pinion-wheels; and in the combination of-the toothed4segments, pinion-wheels, shaft, and pawl with each other, :ind with themovable and stationary parts of the beclstead, the whole bein'gconstructed and arrangedas hereinafter more fully described.

A isth'e foot rail. B is'the head rail. i C and D are the side rails,and are the slats. The side rails G and D are jointedl as shown in figs.1 and 2. ll? are toothed segments of circles, the centres of which arepiv- -otcd to the stationary parts of the said side rails, and one ofthe arms or .sides of which is securely attached to the movable parts ofsaid side rails. G is a shaft, which revolves in bearings in thestationary parts of the side rails, and to'4 which are attachedpinion-wheels H in such positions that their teeth may mesh into theteeth of the segmentsV One of the ends ofv the shaft G projects throughthe side rail, and is squared off so as to -receive ,the crank by. whichit is operated tov lo'wer and raise the said movable part ofv thebedstead. I is a pawl, which is pivoted to the side rail ofthe bedsteadin such a position that it may take hold of the teeth of thepinion-wheel H, and hold the mevablepart of the bedstead stationary inwhatever position it may be placed. J is a spring attached to the siderail in such a position that it may hold the pawl I forward against thepinionwheel. A number of the slats E at the head of the bedstead isconnected together by short longitudinal bars e,to which are attachedthe sides'of'the toothed segments K, the centres of which are pvotedtothe side rails of .the bedstead, and which are operated to raise andlower the said 'movable slats by a shaft and pinion-wheelsV in themanner hcreinbefore described.

What I claim as new, and desire to secure by Letters Patent, is- 1. Theconstruction and arrangement of the foot part hinged to the m'ainportion by means ofthe segments F, and operated by means of the shaft Grand pinion as herein set forth for the. purpose specified.

2, The construction and arrangement of the pawl I 'and spring J, pivotedto the. side of the main portionof the bedstead, as and for the purposespecified.
